Need help with The Norn Fighting Tournament

So im trying to beat this quest with my elementalist and i can beat every single opponent that they throw at me with me nuker build excluding the two most important ones that i want to beat, those two being Zho/Onyx and Magni The Bison himself. I want to beat Zho so i can get her journal and start making the black moa chick mini pet and Magni The Bison because I want to complete the quest, so if anyone could give me a build for my ele or some tips to beat these two hard enemies from The Norn Fighting Tournament, it would be greatly appreciated. Thanks in advance
